601 clock rate rounding through the clock framework can use this

603 harmless for CPUs that don't support rate rounding. The driver
604 will also generate a notice in the boot log before disabling
605 itself if the CPU in question is not capable of rate rounding.

624 help
625 kexec is a system call that implements the ability to shutdown your
626 current kernel, and to start another kernel. It is like a reboot
627 but it is independent of the system firmware. And like a reboot
628 you can start any kernel with it, not just Linux.
629
630 The name comes from the similarity to the exec system call.
631
632 It is an ongoing process to be certain the hardware in a machine
633 is properly shutdown, so do not be surprised if this code does not
634 initially work for you. It may help to enable device hotplugging
635 support. As of this writing the exact hardware interface is
636 strongly in flux, so no good recommendation can be made.

666 the process as file descriptors supporting the read/write
667 syscalls, it's possible to isolate those applications in
668 their own address space using seccomp. Once seccomp is
669 enabled via prctl, it cannot be disabled and the task is only
670 allowed to execute a few safe syscalls defined by each seccomp

680 This enables support for systems with more than one CPU. If you have
681 a system with only one CPU, like most personal computers, say N. If
682 you have a system with more than one CPU, say Y.
683
684 If you say N here, the kernel will run on single and multiprocessor
685 machines, but will use only one CPU of a multiprocessor machine. If
686 you say Y here, the kernel will run on many, but not all,
687 singleprocessor machines. On a singleprocessor machine, the kernel
688 will run faster if you say N here.
689
690 People using multiprocessor machines who say Y here should also say
691 Y to "Enhanced Real Time Clock Support", below.
